What is cadaverine and putrescine?
Putrescine (butane-1,4-diamine) and cadaverine (pentane-1,5-diamine) are foul-smelling compounds produced when amino acids decompose in decaying animals. Putrescine is formed by the decarboxylation of ornithine and arginine; cadaverine by the decarboxylation of lysine.
Is putrescine a polyamine?
Three polyamines, putrescine, spermidine and spermine, are part of the very tightly regulated polyamine metabolic pathway. Polyamines are the subject of intensive research in order to elucidate their functions and involvement in physiology.
What functional groups are in putrescine?
Putrescine, also known as 1,4-butanediamine or 1,4-diaminobutane, belongs to the class of organic compounds known as monoalkylamines. These are organic compounds containing an primary aliphatic amine group.
What type of compound is putrescine?
diamine
Putrescine is an organic compound with the formula (CH2)4(NH2)2. It is a colorless solid that melts near room temperature. IIt is classified as a diamine. Together with cadaverine it largely responsible for the foul odor of putrefying flesh, but also contribute to other unpleasant odors.
What is Cadaverine used for?
Cadaverine plays an important role in cell survival at acidic pH and protects cells that are starved of inorganic phosphate, Pi, under anaerobic conditions [1], [2]. In plants, it is involved in regulating diverse processes such as plant growth and development, cell signaling, stress response, and insect defense [3].
How is cadaverine produced?
Cadaverine is synthesized through the direct decarboxylation of L-lysine, which is catalyzed by lysine decarboxylase in living cells. On the other hand, great progress has been achieved in cadaverine production by direct fermentation of metabolic engineering strains or by whole-cell bioconversion from L-lysine.
What does Cadaverine mean?
Definition of cadaverine : a syrupy colorless poisonous ptomaine C5H14N2 formed by decarboxylation of lysine especially in putrefaction of flesh.
